Calcium supplements can help make your bones stronger, but several conditions need to be met. First, your body needs enough vitamin D to help absorb calcium. Second, the amount of calcium intake should be moderate; too much or too little isn't good. Additionally, exercise and a healthy lifestyle are very important. Osteoporosis is not just a calcium deficiency issue but involves overall bone health. So, taking calcium supplements is just one part of it; a comprehensive lifestyle adjustment is also needed.
